l j Specification forming part of;Let1ers Patent No. 107,782, dated September .'27, i670..

.To all whom at may concern:

Be it known that I, J. HENRY JENINGs, of

`New Bedford, in the county of Bristol and a full, clear, vand exact description of the construction and operation of the same, reference being had to the annexeddrawings, making a part of this specification, and tothe letters and Figure l of the drawings isa representation of central longitudinal Vertical section of my invention. Fig. 2 is a planview of the same. Figs. 3 and 4 are details.

My invention relatesto an improvement in thill-couplings; and it cnsists in the construction and novel arrangement of devices deserving a tight joint.

The letter A of the drawings represents the shaft-iron, `at the end of which is formed a transverse Sleeve, B, through which passes the hinge-bolt C. `D represents that portion of the coupling which is attached to the axle.

E designates amovable piece placedbetween b Y l l, the sleeve B and the rear `wall of the recess in the part l), behindthe same. This movable piece consists of `two horizontal plates, a a', connected bya semicircular partition, b, which a V is centrally slotted at c.` The upper plate, a,

`has ,more breadth than the lower one, a',

,purpose in precavo-convex partitionb, the convex side of which is turned toward the rubber.

I-I designates a small block of rubber, inserted through the slot c, and projecting suffi eiently,

both in front and in rear, -topress against theV sleeve B and the rubber cushion F. The action "of the rubber is constantly to press the piece E forward against the sleeve B; yet it is' not always in contact therewith Onaccount of the `block H. Unduefriction is thereby pre Vented.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In combination, the thill-iron movable piece E, axle-iron D, rubber cushion F,

and rubber block H, substantially as shown and described.

2. The movable piece E, consisting of the horizontal plate a af, connected by the concav`o-ccnveX partition b, slotted centrally, substantially as specified. l

In testimony that I claim the above I have hereunto subscribed my name in thepresence of two witnesses.

J. HENRY JENINGS.
